--------------------------------
Summary: Setting struts.devMode from system property not working as described
Key: WW-4928
URL: https://issues.apache.org/jira/browse/WW-4928
Project: Struts 2
Issue Type: Bug
Components: Core
Affects Versions: 2.5.14.1
Environment: **Windows, Linux, Solaris
Reporter: Peter J Ford
According to [http://struts.apache.org/core-developers/constant-configuration.html] the struts.devMode
setting can be read from environment strings or system properties. This works correctly when
setting from an environment string - for example:
{{<constant name="struts.devMode" value="${env.STRUTS_DEV_MODE:false}"/>}}
However it does not work for system properties, such as setting "-DstrutsDevMode=true" as
a system property and this in struts.xml:
{{<constant name="struts.devMode" value="${strutsDevMode:false}"/>}}
Having dug through the source I found that this is to do with the way the value substitutor
is configured, and that using ":-" instead of ":" as the separator string when using system
properties will work:
{{<constant name="struts.devMode" value="$\{strutsDevMode*:-*false}"/>}}
